SQL injection (SQLi) is a type of cybersecurity attack that targets web applications and can have serious consequences if successful. It occurs if an attacker is able to inject malicious into a database query . SQL injection attacks can lead to data breaches, unauthorized access, and data manipulation.
SQL injection attacks typically target web applications that accept user input, such as search boxes, login forms, and registration forms. Attackers enter into these input fields. For example, they might input ' OR 1=1 -- into a login form's username field. If the web application does not properly validate or , it may directly incorporate the attacker's input into SQL queries without proper checking.
To prevent SQL injection, it is important to validate and sanitize all user input before using it in SQL queries. This includes using or prepared statements. Additionally, using stored procedures whenever possible can help encapsulate database logic, reducing the risk of SQL injection by separating user input from SQL code. It is crucial to employ these methods to ensure the security of web applications against SQL injection attacks.
